Yes you do. Flywheel on the Semi's are very heavy and in order to sync right you have to double clutch.

Is a semi automatic better than a manual shifter?
IMO also the fact is yes it is better than conventional manual, the paddle shifters behind the wheel to change gears & it's clutch less. It has a robotized clutch & the shifting are much quicker/faster than with stick shift manual. Even the best/experienced driver can't change gears as fast using clutch as the semi auto. Semi auto changes gears faster will result with better acceleration & has the advantage in races. They really benefits for F1 cars & now for many exotic cars.
Do you have to double clutch a semi to Chang gears?
Nope, you don't even have to single clutch... I work with a few people who only touch the clutch when making a full stop. Personally, I think it's hard to do, and I single clutch. If you're ever testing with DOT, you best make sure you're double clutching though, because that's the "correct" way to shift, in their book.

Does a F1 driver change gears?
Formula One cars use semi-automatic sequential gearboxes with six or seven forward gears and one reverse gear. The driver initiates gear changes using paddles mounted on the back of the steering wheel and electro-hydraulics perform the actual change as well as throttle control. Clutch control is also performed electro-hydraulically except from and to a standstill when the driver must operate the clutch using a lever mounted on the back of the steering wheel. Taken from http://en.wikipedia.org/wiki/Formula_One_car Hope This Helps.
Can you stop a semi truck in high range with the clutch pressed?
Not with the clutch by itself.
Does it matter how many gears you have when changing a clutch?
Absolutely not. The clutch should be between the motor and the transmission, you should never have to open up the transmission to change the clutch unless you have one of those dual-clutch semi-auto paddle shifter cars, and then I wouldn't even try fixing that unless I had fairly extensive transmission experience, which, if you're asking this, I'm guessing you don't. Changing a clutch can be fairly easy on some cars, and fairly hard on others, the hardest part is lining up the clutch plate while bolting on the pressure plate; it must be perfectly aligned or it will be impossible to reinstall the motor.
How does semi automatic transmission in a car work?
Semi automatic transmission is usually the one which is fitted into a car with manual transmission. The manual transmission requires pressing clutch to change gears or to stop. If you don't press clutch pedal and change the gear, it will do a serious damage to your gear box. In semi automatic transmission system, the clutch is very much in place, but the only difference is you don't have to do it manually. It has a motor and an electronic device that senses the speed, the gear change and brake pressure and then presses or depresses clutch automatically. Advantage of this system is you can take the pleasure of automatic transmission in a manual vehicle. The semi automatic systems however has some flaws. If need to get used to it a bit. You have keep rpm pretty high in this system. Taking a start motion in first gear could be a problem. If rpm is on a bit lower side, you clearly feel the lag while driving. It is a system best suited to physically challenged drivers who have problem using one of the feet. Of course, the better alternative is fully automatic transmission that does away with the clutch altogether. But is far more expensive and is available only in select models.
How often use the clutch brake in a semi truck?
